Power Calculations

Lesson Prerequisites

This lesson assumes that you have completed the Statistical Inference lesson or a course in hypothesis testing. This lesson also assumes that you have beginner Stata skills and can complete the exercises in the lessons on Intro to Stata and Stata Best Practices. The last module requires Stata version 15 or later to compute power for a clustered design using the power command. If you have an earlier version of Stata, then you will need to use a different command to do clustered power calculations; we recommend the user-written clustersampsi command.
